During the use, the flue gas passes through the pipeline, and the pipeline is heated, and the running water passes through the cavity, with the pipeline cooling, and the running water that heats simultaneously flows into hot water pipeline, can provide hot water, and this heat that contains in the just make full use of flue gas.
Description
Technical Field
The utility model relates to an exhaust pipe.
Background
The equipment heated by burning fuel, such as gas air conditioner, gas water heater, etc., can produce a great deal of smoke and dust when in use, therefore, the equipment is provided with a channel for discharging smoke and dust, namely an exhaust pipe, and the smoke and dust is discharged through the exhaust pipe in the burning process. The smoke exhausted from the exhaust pipe contains a large amount of heat, which is lost and leaked into the air, so that improvement is needed.
Disclosure of Invention
The utility model provides an exhaust pipe to not enough among the prior art, the heat that contains in can the make full use of flue gas.
In order to solve the technical problem, the utility model discloses a following technical scheme can solve: the exhaust pipe comprises a pipeline, wherein a circle of sleeve is arranged on the outer ring of the pipeline, a circle of sealed cavity is formed between the sleeve and the pipeline, water is arranged in the cavity, a water inlet and a water outlet are formed in the outer wall of the cavity, the water inlet is connected with a tap water pipe, and the water outlet is connected with a hot water pipeline. During the use, the flue gas passes through the pipeline, and the pipeline is heated, and the running water passes through the cavity, with the pipeline cooling, and the running water that heats simultaneously flows into hot water pipeline, can provide hot water, and this heat that contains in the just make full use of flue gas.
In the above technical solution, preferably, the pipe has a bending portion, the bending portion bends downward, the outlet of the pipe faces the ground, and the sleeve is disposed at an outer ring of the bending portion. The bent part is arranged downwards, so that dust accumulated in the pipeline can fall freely under the action of gravity to avoid accumulation, meanwhile, the sleeve is arranged at the bent part, the airflow at the bent part turns 90 degrees, and the airflow at the bent part collides with the pipeline most intensely, so that the heat exchange area is the most ideal area.
In the above technical solution, preferably, the pipeline is provided with a circle of protrusions. The protrusion is used for positioning when the pipeline is connected with a smoke outlet of a water heater or an air conditioner.
In the above technical scheme, preferably, the sleeve includes a section of bent pipe and end covers disposed at two ends of the bent pipe, one side of the end cover, which is close to the sleeve, is provided with a circle of first baffle, and the first baffle is in contact with an inner ring of the bent pipe.
In the above technical scheme, preferably, one side of the end cover, which is close to the elbow pipe, is provided with a circle of second baffle plate, and the second baffle plate is in contact with the outer ring of the elbow pipe.
The utility model has the advantages that: during the use, the flue gas passes through the pipeline, and the pipeline is heated, and the running water passes through the cavity, with the pipeline cooling, and the running water that heats simultaneously flows into hot water pipeline, can provide hot water, and this heat that contains in the just make full use of flue gas.

Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
referring to fig. 1 to 4, the exhaust pipe comprises a pipeline 1, wherein a circle of sleeve 2 is arranged on the outer ring of the pipeline 1, a circle of sealed chamber 3 is formed between the sleeve 2 and the pipeline 1, water is arranged in the chamber 3, a water inlet 31 and a water outlet 32 are arranged on the outer wall of the chamber 3, the water inlet 31 is connected with a tap water pipe, and the water outlet 32 is connected with a hot water pipeline.
The pipeline 1 is provided with a bent part 11, the bent part 11 is bent downwards, the outlet of the pipeline 1 is towards the ground, and the sleeve 2 is arranged at the outer ring of the bent part 11. The bent part is arranged downwards, so that dust accumulated in the pipeline can fall freely under the action of gravity to avoid accumulation, meanwhile, the sleeve is arranged at the bent part, the airflow at the bent part turns 90 degrees, and the airflow at the bent part collides with the pipeline most intensely, so that the heat exchange area is the most ideal area.
A circle of bulges 12 are arranged on the pipeline 1. Referring to fig. 4, the protrusion 12 functions to provide a location for the pipe when it is connected to the water heater or air conditioner flue gas outlet 4.
The sleeve 2 comprises a section of bent pipe 21 and end covers 22 arranged at two ends of the bent pipe 21, wherein one side, close to the sleeve, of each end cover 22 is provided with a circle of first baffle plates 221, and the first baffle plates 221 are in contact with inner rings of the bent pipe 21. A ring of second baffles 222 is arranged on one side of the end cover 22 close to the elbow pipe 11, and the second baffles 222 are in contact with the outer ring of the elbow pipe 11.
During the use, the flue gas passes through the pipeline, and the pipeline is heated, and the running water passes through the cavity, with the pipeline cooling, and the running water that heats simultaneously flows into hot water pipeline, can provide hot water, and this heat that contains in the just make full use of flue gas.
